[Studies of the antistreptolysin titer in patients with acute pneumonic processes]

Antistreptolysin O level in blood serum is determined in double tests in 164 patients, 116 out of them with acute pneumonic processes. Antistreptolysin titre was established to be over 300 ASE in about 1/5 of the patients with acute focal pneumonias. In 10,4 per cent of the cases with acute pneumonic processes, an ascending dynamics of antistreptolysin O titre is observed in the course of the treatment and in 2,6 per cent the titre elevation is three and fourfold. In the interpretation of the data of the antistreptolysin titres in patients with acute focal pneumonia the possibility of oculte streptoccocal infection with another localization must not be neglected as well as pathological processes in liver parenchyma, leading to non-specific titre elevation.
